Duodenal leiomyoma associated with colic in a two-year-old horse

Abstract

A 2-year-old horse with signs of colic, reflux on nasogastric intubation, and large colon distention on transrectal palpation was found to have a leiomyoma involving the duodenum. The mass was excised without penetration of the lumen of the small intestine, and the horse recovered without complications.
